Abstract

Aparato de decodificación de imágenes que recibe una señal codificada (80a, 80b, 82a y 82b) de una imagen y decodifica dicha señal codificada, que comprende: una unidad de decodificación de valores de pixel (83a) que puede utilizarse para decodificar un valor de diferencia codificado (82a) de la señal de valor de pixel incluido en la señal codificada para obtener una señal de valor de pixel de diferencia codificada de una imagen de destino; una unidad de decodificación de vectores de movimiento de valor de pixel (81a) que puede utilizarse para decodificar un vector de movimiento de valor de pixel codificado (80a) incluido en la señal codificada para obtener un vector de movimiento de valor de pixel decodificado de la imagen de destino; una primera unidad de compensación de movimiento (63a) que puede utilizarse para compensar una señal de valor de pixel de una imagen de referencia mediante el vector de movimiento de valor de pixel decodificado de la imagen de destino para obtener el resultado de la compensación de movimiento como señal de valor de pixel compensada de la imagen de destino, y una unidad de cálculo (84a) que puede utilizarse para sumar la señal de valor de pixel de diferencia decodificada de la imagen de destino y la señal de valor de pixel compensada de la imagen de destino para obtener el resultado (85a) de la suma como una señal de valor de pixel decodificada de la imagen de destino.
